Improvement of damping characteristics of structural members with high damping elastic inserts
Abstract
The major objective of this work is to investigate theoretically the possibility of improving the damping capacities of structural members with the help of inserts of special high damping materials. The inserts have been considered to be both welded and press-fit to the members. It has been observed that the effectiveness of the press-fit inserts is much more than that of the welded inserts. In case of the welded inserts there exists an optimum size whereas for shrink-fit inserts best results are expected when the inserts are solid. It has been found that with such a method the damping capacity of a member can be considerably increased with no significant loss in static rigidity.
